We have a bum-strap that clips to eyes on either side of the stove. You can brace yourself with your feet and the strap behind your bum to work on the stove or on the shelf that comes down over the stove. Works pretty well.
Back in the water in Grenada - with new main and #2 and cockpit canvas (Santa came early). Will spend the winter and early spring in the Caribbean and then head to Bermuda and the northeast US. Still trying to decide if we will bring the boat to Canada, either in 2015 or 2016.
